Description
Technical Field
The invention relates to the technical field of power automation system testing, in particular to a multi-power system testing method based on a virtualization platform.
Background
At present, various electric power automation systems (electric power systems) continuously upgrade, update and perfect various functions, and especially when the functions of an electric power terminal such as control are upgraded and updated, the correctness and stability of the functions must be tested before the system is put into operation, such as a dispatching automation system and a power distribution automation system.
The following is an illustration of a dispatch automation system:
The domestic power grid dispatching automation system is a layered dispatching management system, and the multi-stage systems can be coordinated up and down only by connecting a network during testing, and the multi-stage systems are mutually matched to realize testing before operation of various coordination interaction functions of the multi-stage systems.
Because the dispatching automation system belongs to the power grid core system, the on-site network environment is provided with an intranet special purpose. If any abnormal phenomenon occurs in the real system operation before upgrading due to the upgrading test of the functions, the operation is strictly forbidden. When the updated functions of the multi-level dispatching automation system are tested conventionally, the following means are adopted:
And according to the requirements of the automatic system with different dispatching, individuating entity machines meeting the conditions to finish the application construction of the system. Because the different dispatching automation systems have differences on the computing capacity and the storage capacity demands of the physical machines, the system and the physical machines are often tightly coupled after configuration is finished, so that the utilization rate of the physical machines is greatly reduced after the test work is finished, and the waste of material resources is caused.
When a plurality of similar dispatching automation systems need to be tested at the same time, the installation of the operating system and the configuration of the conventional system still need to be completed on the physical machine one by one, the repeated workload is large, and the time is consumed.
In order to avoid influencing the network environment where the real system is located, when the upper-level automatic system needs to perform functional test with a plurality of lower-level automatic systems at the same time, network equipment such as corresponding routers, switches and the like needs to be purchased and added, and the network environment independent of the real production system is temporarily built for the entity machine. On the one hand, the equipment is relatively expensive and consumes a great deal of funds; on the other hand, the utilization rate is reduced after the test work is finished, and the equipment is in a long-term empty state.
The message interaction between the upper and lower stages of the dispatching automation system is usually realized based on a DL476 power communication protocol, and the upper and lower stages of the system interaction in the test process needs to be manually checked to confirm whether the instruction transmitted by the system is correct or not, and the manual confirmation process consumes time to influence the instruction execution efficiency.
When the existing dispatching automation system issues the instruction to the terminal, the terminal action is realized by completing the instruction outlet at the terminal instruction outlet sub-station independently built by each subordinate dispatching automation system. Because of the slight difference of different manufacturers to the specific design of the terminal instruction output substation of the dispatching automation system, when the terminal is accessed to the dispatching automation system of different versions, corresponding configuration is required to be completed respectively according to specific requirements, when the terminal is accessed to the system to change the version, corresponding access configuration is required to be synchronously changed, and if the number of the terminals is large, the debugging workload is also increased in proportion.
In order to solve the problems, the invention provides a multi-power system testing method based on a virtualization platform.

and after receiving the control execution instruction, the lower-level electric power automation system replies the control execution instruction operation, and after receiving the control execution confirmation message fed back by the lower-level electric power automation system, the upper-level electric power automation system completes the third handshake.

The electric power automation systems at all levels are subjected to network configuration, so that data and instructions among the electric power automation systems can be communicated through network connection.
Based on a DL476 load batch control interaction protocol, adding message types corresponding to real-time data and control instruction interaction, and establishing and debugging a data transmission channel between the multi-stage power automation systems through an instruction 'three-way handshake' between the upper and lower-stage power automation systems;
The real-time data and the control instructions need to be converted into the agreed JSON format byte stream for transmission, the interactive instructions among the multilevel systems are confirmed in the test process, compared with the traditional XML format, the JSON format requires complicated and heavy labels, when the transmission quantity is large, the occupied network flow is not negligible, the interactive contents of the real-time data and the control instructions are converted into the lightweight JSON format byte stream form for transmission, the reading and writing of people are easy, and meanwhile, the machine analysis and generation efficiency is improved.
The instruction "three-way handshake" between the upper and lower electric power automation systems, as shown in fig. 2, specifically includes:

In practical application, if the instruction issued by the upper system is an exercise instruction, the terminal is not required to actually act, and the instruction is not transmitted to the terminal instruction output sub-station, so that the terminal instruction output sub-station is not required to be established.
Optionally, after the virtual machine is created on the virtualization platform and the network configuration is completed, a system snapshot can be created on the virtualization platform for each level of electric power automation system, and when the function debugging is wrong, the electric power automation system can return to the normal running state at the time of creating the snapshot again.
Because of the unknown defects of the development program of the new function, uncontrollable testing process exists. If the system runs and the system still cannot normally run after the program is adjusted and modified, the normal running state of the system at the time of creating the snapshot can be quickly returned based on the system snapshot created by the virtualization platform, the system is prevented from being reloaded, and the system repair time is shortened.
